GG&G developed the Shockwave Flashlight Mount specifically for the Shockwave because the foregrip of the Mossberg Shockwave is a reconfigured version of Mossberg's 590 foregrip. Our 590 flashlight mount which is similar, is a hair too close to the foregrip, so if you own one of the new Mossberg's and need a flashlight mount, this is the one to get!
